AWS Certified Solutions Architect - Professional SAP-C02 — Topic 1 Question 150

Question

A company has a latency-sensitive trading platform that uses Amazon DynamoDB as a storage backend. The company configured the DynamoDB table to use on-demand capacity mode. A solutions architect needs to design a solution to improve the performance of the trading platform. The new solution must ensure high availability for the trading platform. Which solution will meet these requirements with the LEAST latency?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Create a three-node DynamoDB Accelerator (DAX) cluster. Configure an application to read data by using DAX and to write data directly to the DynamoDB table. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. DynamoDB Accelerator (DAX) adds an in-memory cache for microsecond DynamoDB reads. AWS Config tracks resource configuration changes and evaluates compliance.
